We're dividing 630904 by 49 
We want to divide 630904 by 49.

Advancing to step 1:
49 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 49

On to step 2:
49 can be fit into 63 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 49 from 63 to get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 49

Going ahead to step 3:
The number 49 fits into 140 2 times, leaving a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 98 from 140, we get 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 49

Moving on to step 4:
49 goes into 429 8 times with a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 128.0
If we subtract 392 from 429, we get 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 49

Step 5:
49 goes into 370 7 times with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 1287.0
If we take 343 away from 370, we end up with 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 49

Let's proceed to step 6:
When dividing 274 by 49, we get 5 with a remainder of 29.
Use 5 as the next digit of our solution. 
Result so far: 12875.0
If we subtract 245 from 274, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
290 divided by 49 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 12875.5
Deduct 245 from 290 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
49 goes into 450 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 12875.59
Subtracting 441 from 450 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
90 divided by 49 is 1 with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 12875.591
The remainder is 41 after subtracting 49 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
When dividing 410 by 49, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 12875.5918
Subtract 392 from 410 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
49 goes into 180 3 times with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 12875.59183
Deduct 147 from 180 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 12:
330 divided by 49 is 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 12875.591836
The remainder is 36 after subtracting 294 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
If we divide 360 by 49, we get 7 and a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 12875.5918367
Deduct 343 from 360 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
49 can be fit into 170 3 times, resulting in a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 12875.59183673
If we subtract 147 from 170, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 12875.59183673, with a leftover of 2.3e-08.
